The free and Open-source iOS Synth AudioKit Synth One has added a free color-coded microtonal keyboard.
Users can now explore non-western alternative scales using one of the 100+ included curated scales. And, musicians can import their own Scala (scl) files.
Key colors on the new keyboard match pitch wheel colors on the "Tune" panel for intuitive performance. For those that want to dive deeper, the full source code is also freely available.
Synth One version 1.1 with new Microtonal capabilities is now available for both iPhone & iPad as a free download in the App Store.
Volunteer developer and microtonal researcher Marcus Hobbs, creator of the free scale tool Wilsonic, contributed the microtonal code and keyboard interface for Synth One.
AudioKit Synth One requires iPhone 6 and above or, iPad 4 or above.
